Diathermic oil heating electric groups

RO 11 RO 24

The heating electric groups are specifically designed for a controlled and homogeneous heating of diathermic oil. Made up of one or more armored electric heaters immersed in diathermic oil, they keep the oil moving thanks to a pump in forced circulation which is managed by a temperature control unit of the fluid, avoiding the risk of an accidental rise of the temperature to a critical overheating level.

Constant temperature is obtained thanks to the interaction between a dilating thermostat and a PT100 probe which transmits a signal (in mA) to a thermoregulator. In case of a failure of the controlling thermostat, a safety thermostat with manual restart immediately interrupts the power supply of the control unit. The diathermic oil from the heating unit is transferred to an industrial process (for example the heating of a tank).

Application fields: processing of raw materials, heating of tanks, serigraph industry, processing of resins and plastic materials, processing of paints and solvents, furniture industry, cosmetic industry, food industry.

Frequently asked questions

Yes, they are available in sealed execution or ATEX II 2 G execution, for use in classified areas of the chemical, petrochemical and process industries.
The RO groups reach an overall power of up to 36 kW, thanks to 4 modular heater housings; typical models include the RO 11 and the RO 24, sized according to the volume of oil to be heated and the required temperature delta.
Control is achieved through a dilating control thermostat paired with a PT100 probe connected to a thermoregulator; a second, independent safety thermostat with manual reset immediately cuts the power supply in case of a fault.
Yes, in addition to diathermic oil the unit can be used for controlled heating of forced-circulation water, keeping the same operating principle with pump and temperature control.
Yes, an optional PLC is available for automatic management of the heating cycle, together with a multifunction electric panel that can be configured to the plant's specific needs.
They are used in raw material processing, tank heating, the serigraphy industry, resin and plastic processing, paints and solvents, as well as in the furniture, cosmetic and food industries.
